+++ Anthropic quietly built geolocation tracking into Claude Code, got caught, and rolled it back after backlash, while Meta simultaneously discovered it needs fortress-level restrictions to prevent their own engineers from accidentally distilling the thing. +++
+++ Anthropic released Claude Sonnet 5, claiming near-Opus 4.8 performance at better prices and notably improved agentic capabilities, which is exactly what you say about every mid-tier model release. +++
+++ Anthropic wrapped Claude in a scientific workbench that connects to 60+ databases, proving that the real moat isn't the model, it's knowing what to plug it into. +++
+++ Anthropic's latest Claude versions are no longer export-controlled, arriving Wednesday via credits while the company joins rivals in defining what "jailbreak" actually means legally. +++

"Metacognition is a critical component of intelligence that describes the ability to monitor and regulate one's own cognitive processes. Yet LLMs exhibit systemic deficiencies in key metacognitive faculties: they hallucinate with high confidence, fail to recognize knowledge boundaries, and misreprese..."
"We discover a behavioral invariant in LLM agents under persistent memory poisoning: in architectures where routing information is retrieved through observable memory-tool invocations, successful attacks require calling memory_recall_fact before email_send_email, a transition that non-exfiltrating se..."

"Modern AI evaluation frameworks treat evaluator disagreement as noise to be resolved. In creative domains, professional disagreement reflects genuine differences in taste, not measurement error. We argue that evaluating creative AI requires preserving two distinct signals: convergence, where profess..."

"Residual-stream analysis asks how language-model computation evolves across depth, but intermediate decoding requires comparable readout coordinates across layers. If embedding anchors and unembedding readout disagree on the chosen span, apparent motion may reflect measurement drift rather than comp..."

"We introduce Agents-A1, a 35B Mixture-of-Experts Agentic Model that reaches trillion-parameter-level performance by scaling the agent horizon. We investigate agent-horizon scaling from two perspectives: scaling long-horizon trajectories and scaling heterogeneous agent abilities. To support this goal..."

"While large language models (LLMs) perform well on table tasks, they still make data referencing errors (DREs), i.e., incorrectly citing or omitting table values, despite understanding the table structure. Beyond final-answer accuracy, DREs directly compromise the correctness and reliability of inte..."

Progress on this challenge requires understanding real workload patterns, yet the data needed for such analysis is largely absent. Existing public traces and benchmarks do not ca..."

However, unreliable foresight can be ignored, misused, or even degrade downstream decision-making. In this paper, we introduce WorldEvolver, a self-evolving world..."

"Conservative offline training is widely advocated as a safe foundation for subsequent online adaptation: if a policy stays close to well-supported behaviour, the argument goes, it is less likely to exploit imperfections in a learned reward model. We challenge this intuition empirically and mechanist..."
